converting audio from spanish to english

I have a movie that is in spanish and I want to convert it to english if its possible what do I need and how do I do it...

Thanks in advance

 

Not possible. If you know Spanish, you could translate it yourself and do a voice over, otherwise, not possible. Look for the English version or English subs...

 

Thanks just thought I would see if its possible

 

or you could look for just the English sound track (ooo.. that's a very scene thing to do) and mux it together.
